CAR-TRUCK slim FRAME.

Patented Sept. 5, 191?.

Application filed February 3, 1911. Serial No. 606,876.

' To all whom it may concern:

Be itknown that I, Vio'roR 1V1. SUMMA, a citizen of the United States, residing atlleb' ster Groves Missouri, have invented a rer- ,6 tain new and useful Improvement in Car- Truck Side F rames, of which the following is afull, clear, and exact description, such as \vill enable others skilled in the artto which it appertains to make and use the same.

This invention relates to side frames for car trucks.

The main object of my invention is to pro- .vide a strong and serviceable truck side frame that can be manufactured at. a low 1 cost.

Another objectis to providea side frame that can be built from commerciallyq-olled members or pressed members and metal plates. And stillanother objeot is to pro- ..vide a strong and inexpensive-side frame of girder cons trl lction lthat is constructed to rea 'peivea bolster provided with integral column Other objects and desirable features of my invention will ,behereinafter pointed out. A

:Fig'urel of-the drawings is a side elevational view of a car truck side. frame Tconstructed in accordance withmy invention; Fig. 2 is atop plan view partly in horizon talsection taken on the line -2-2 of Fig.1; Fig. 3 is a v-ert-ical sectional view taken. on

the line Mao i-Fig; 2;,Fig. t is'aside elevational vierv oi one of the web p1ates;.Fig. 5 .isw. perspective, vie of said web. plate;

Fig. 6 is a crosssectional view illustrating a pressed: metahmember usedto form the top chord-of the side-frame; Fig. 7 is a side elevational View ;of a-web plate of slightly dif- 4 ferent construction from the one shown in Fig. 4; Fig.8 is, a side elevational view illustratin Ethe .weblplate shown in Fig. 7 embodie Fina side, frame; and Fig. 9 1s a side elevational.viewillustrating a. web-plate of slightly diflierent construction front-the one my invention shown in Fig. 1', four web p preferably a channel-sha-p nected to the bottom chords 2 of the saveide 6, plate 'a' aroused; two ofyfsaid-pxlates'being arranged on opposite sides of e members nel-shaped pressed members, as shown in Fig. 6. While I prefer to use chant-eh shaped members to form the top and bottom chords of the side frame I CQlll(l ,.OfCOi. use members or a different shape in section and therefore I do not wish it i. understood that my invention is limitec; to a girder side frame having ehaimel-shaped chords.-.

Theweb plates 3 are connected to the aide flanges of the top and bottom members in may suitable manner as, for example. by means of rivets 4: or other suitable fastening devices, and said plates are provided at their outer ends \vit-hlaterally projecting stiffening flanges 5 and at their inner ends with laterally projecting flanges tig'said flanges 5 and, 6 being formed integral with the Web plates, as herein shown, or formedfrom pieces of angle iron. The flanges G ef the pair of web plates ateach side of the bolster opening project- ;inwardly, tqwar-dz each other, as shown in Fig.3, sQJ-as to form the inner faces of bolster columns which have relatively wide bearing surfaces fortlie side face of thebolstenB -and saicl ,pla'tps are notched out. orkcut away. at;;7 below said flanges 6, so as. to providen filearaneetor the integral column guides B1 on th" bolster ,when the bolster .is being reindvedi for m ranged in operative position. E i'ch pan of. web plates is spaced apart a distance mp.-

. proximately. equal to thespacebetweeii euvh pair ofcolu nn uidesBL q'nthe bolster so that said Web plates ill'act eo'lpinn for the bolster,.andlsaid' yvebf plates ar so 111.-

ran' edthatthe lipper contracted portion of the"- ('Slster openmg A wilhreceive thelmlster snugly 'and thus prevent the Ibolste'i from moving longitudinally oft-he side frames.

, Aspring plank 8 ofanyegreferied design, menner s co frames of the truck, and the end ortions of the top and bottom members each side frame are connected. together by through bolts Qwhich are so arranged that openings are provided for the ournal-boxes, said bolts 9 passing throughopenings 10 in the "v to form the vertical web of the side horizontal webs of said top and bottom members. If desired, the web plates can be provided with hand-holes 11 so as to enable the brake-shoes tobe gotten at easily.

A side frame of the construction above descril'md is exceptionally strong and light because it is a girder composed of'commencially-rolled men'lbers or pressed members and metal plates. 'It can also be built at a low cost and repaired easily, and another desirable feature is that the size and'dimensions of said side'frame can be modified to meet diiferent conditions or requirements.

g-While I prefer to use four separate fplates rame,

said web could be formed from two plates 3*,

as shown. in Figs. 7 and 8, each of which is bent or doubled on the dotted lines X in Fig.

'1' so as to formtwo side portions g which are umnected to the top and bottom chords, and

- :11. intermediate portion 2 that ties the porsired, a p ct fta-nce abovfeithe lower end of same, asshownin Fig. as to form a. clearance for the cdlumn guides on the bolster.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is I A -truck side frame consisting of a built-up girderwhich is composed of top and-bottom chords whose end portions are spaced away from each other so as to fornr spaces for Journal boxes, and vertically (115 posed web plates connected to said chords.

" "2. A truck side frame provided with top and bottommembers of approximately chanrial-shape in cross section which form the chords of a girder, and web plates connected tothe flanges of said members.

18. A truckside frame consisting of a firder formedfrom flanged top and bottom embersand web plates, said side framehaving ionrnal-boir openingsbetwcenpaid top and bottom members and also a bolst'er opening whose lower portion is of greater width than itsupper portion.

'4. A truck side tion that consists of flanged members which form the top and bottom chords of the girder, and approximately parallel w plates that are connected to said top an.

in downwardly, and vertically *ame of girder construcbottom chords, the end portions of said chords being spaced away from each other so as to provide openings or spaces in which. the journal boxes are arranged.-

5. A truck side frame provided with top and bottom members of substantially channel-shape incross section, and separate verticai'iy disposed web plates connected to the flanges of said members and arrangedin such a manner that an opening is provided for the bolster. v
